Before you upgrade the vRealize Automation virtual appliances and the vRealize Automation IaaS nodes, direct all traffic to the primary node and disable the health check on the NSX load balancer for the management applications.

The configuration change disables the second pool member for the five vRealize Automation VIPs. During an upgrade, the services inside the second node might not be upgraded or initialized because of installation or power cycle operations. If the load balancer passes a request to the second node, the request will fail. If the second pool member remains enabled, you might experience failures during vRealize Automation upgrade, and service initialization or registration failures during a vRealize Automation appliance power cycle operations.

On the NSX load balancer, you disable the secondary vRealize Automation nodes and deselect the monitor for the associated traffic in the pools.
